Symptom: Local MPLS labels change after an SSO causing a traffic drop a for short period of time. Conditions: The symptom is observed when LDP graceful restart is configured and SSO is supported on the platform. Only the prefixes which have a local label but not a remote label before the SSO are affected. After SSO, these prefixes get assigned a new local label. The traffic should recover once the LDP neighbors learned the new labels.
